Angular - Material: Progressbar custom color?

Question

I am now trying for hours. I use Material2 and simply want to change the color of the progress-bar. I know there are those themes (primary/accent/warn) but I want to have a cutom color (green) for my progressbar.

I already tried the wierdest css-combinations.. but with no effort. Maybe someone had the same problem?

Answer 1

Since nobody mentioned so far...

He's how I solved it.

@Meet Dave is right about his approach. But you should use encapsulation: ViewEncapsulation.None (disables css modules)

Something like this:

Component

@Component({
  selector: '...',
  templateUrl: '...',
  styleUrls: ['...'],
  encapsulation: ViewEncapsulation.None,
})

Sass (in my case)

.audio-progress-bar {
  &.mat-progress-bar {
    height: 10px;
  }

  .mat-progress-bar-fill::after {
    background-color: #37474f;
  }

  .mat-progress-bar-buffer {
    background-color: #90a4ae;
  }

  /* remove animation and the dots*/ 
  .mat-progress-bar-background {
    animation: none;
    background-color: #eceff1;
    fill: #eceff1;
  }
}

View

<mat-progress-bar
  class="audio-progress-bar"
  mode="buffer"
></mat-progress-bar>

Update:

Avoid using deep, TL;DR: Deep is technically invalid (like, deeprecated :p)

For more info refer: The use of /deep/ and >>> in Angular 2

Now, to change the color of mat-progress bar, Here is how I got it working,

Head over to your styles.scss file (or the main css/scss file in your project)

Add this class -->

.green-progress .mat-progress-bar-fill::after {
    background-color: green !important;
}

Your mat-progress should use the above class, like -->

<mat-progress-bar class="green-progress" mode="indeterminate"></mat-progress-bar>

Angular 7 and Material 7.1.1

 ::ng-deep .mat-progress-spinner circle, .mat-spinner circle{
        stroke: green !important; 
}

I can suggest to change one of the premade primary/warn/accent colors to your custom color.

In your styles.scss (if your style file is css you will have to change it to support scss):

  @import '~@angular/material/theming';
  // Plus imports for other components in your app.

  // Include the common styles for Angular Material. We include this here so that you only
  // have to load a single css file for Angular Material in your app.
  // Be sure that you only ever include this mixin once!
  @include mat-core();

  // Define the palettes for your theme using the Material Design palettes available in palette.scss
  // (imported above). For each palette, you can optionally specify a default, lighter, and darker
  // hue.

  $mat-blue: (
    50: #e3f2fd,
    100: #bbdefb,
    200: #90caf9,
    300: #64b5f6,
    400: #42a5f5,
    500: #2196f3,
    600: #1e88e5,
    700: #1976d2,
    800: #1565c0,
    900: #0d47a1,
    A100: #82b1ff,
    A200: #448aff,
    A400: #2979ff,
    A700: #2B66C3,
    contrast: (
      50: $black-87-opacity,
      100: $black-87-opacity,
      200: $black-87-opacity,
      300: $black-87-opacity,
      400: $black-87-opacity,
      500: white,
      600: white,
      700: white,
      800: $white-87-opacity,
      900: $white-87-opacity,
      A100: $black-87-opacity,
      A200: white,
      A400: white,
      A700: white,
    )
  );

  $candy-app-primary: mat-palette($mat-blue, A700);
  $candy-app-accent:  mat-palette($mat-orange, A200, A100, A400);

  // The warn palette is optional (defaults to red).
  $candy-app-warn:    mat-palette($mat-red);

  // Create the theme object (a Sass map containing all of the palettes).
  $candy-a-theme($candy-app-theme);
pp-theme: mat-light-theme($candy-app-primary, $candy-app-accent, $candy-app-warn);

  // Include theme styles for core and each component used in your app.
  // Alternatively, you can import and @include the theme mixins for each component
  // that you are using.
  @include angular-material

Answer 5

You can override only progress bar backgroud-color through this method added custom class then apply css by combination of tag and class like-

<mat-progress-bar class="my-color" mode="determinate" value="40"></mat-progress-bar>

Change into style.css

mat-progress-bar.my-color .mat-progress-bar-fill::after { background-color: green; }

Answer 6

Angular 8 solution:

for me it was putting my styling in a top level .scss file. Also had to select in .scss as follows:

html:

<mat-progress-bar [ngClass]="passwordStatusBarColor" 
                  aria-label="Password strength meter"
                  mode="determinate"
                  [value]="progress">
</mat-progress-bar>

<!--passwordStatusBarColor could be 'weak', 'weakest', etc. with a corresponding rule-->

styles.scss:

.weakest {
  .mat-progress-bar-fill::after {
    background-color: yellow;
  }
}
